,Be it known that I, LoUIs HOFFMAN a citizen ofthe United States, residing at uluth,`in the county of St. Louis and State of 5 Minnesota, have invented certain new and useful Improvements in Sad-Irons, of whichv the following is a specification, reference being had thereinto the accompanymg drawing. l

This inventionl consists of certain 1mprovements in sadirons and relates especially to such an iron equipped with means for heating both the iron and water` applied thereto for generating steam. A

The object is to produce a simple and eilicient device of this character having certain novel and advantageous features as will appear from the further description of the device and especially pointed out in the claims. In the accompanying drawings forming part of, this application and in which like reference characters indicate like parts:

Figure 1 represents a longitudinal vertical section of an iron embodying my invention,

6 intermediate the division wall 2 and the bottom 5 of the iron.

The top of the iron is covered by a suitable plate 7 being removably 4fastened thereto in any desired manner, as for example, by suitable screw bolts 8, which construction is common in the art.

yWithin the chamber 9 hereinafter referred to as the combustion chamber and which is formed intermediate the division wall 2 and the cover 7 is placed a narrow flat elongated receptacle 10, which receptacle is positioned on an incline longitudinally within thefiron, that portion in the forward end of the iron being higher than that at the rear end of the iron. This receptacle is for the rece tion of 5o water through the pipe 11 and whic water normally runs to and remains at the rear end of the receptacle, as indicated at 12. The water inlet pipe 11 acts as a support to the center of the receptacle, and the steam discharge pipe 13 at the forward end of the SAD-IRON.

chamber 6 by being screw threaded through Vthe division wall 2 acts as a support to the receptacle which communicates with the clined position. If desired, other forms of I support for the receptacle, either entirely, or as an auxiliary lto the pipe connections, may be resorted to.'

Passing'through the rea-r wall 14 of the iron and adjacent one edge of the receptacle 10 and preferably slightly below same', isa gas plpe'burner 15, said pipe leading'v from any suitable form of'gas supply 16, and just adJacent the rear end of the iron being provided with'a branchpipe 17 which connects with the burner pipe 18 identical with that upon the opposite side. These burner' pipes are provided with suitable numerous perforations 19 through which gas is admitted and burned in the combustion chamber 9.

pointing toward the undermost -edge of the chamber 10 and the otherpointing downwardly and inwardly toward the division wall 2, thus distributing the heatproperlyv within the iron and against the steam generating receptacle 10.

Within the .chamber 6 is suspended a steam dlstributlng tube 20, ithaving an angular branch 22 adjacent the forward fend thereof and which is screw threaded within the division wall 2 and abutting the end of the steam supply pipe 3. This pipev is provided with .preferably two .series of small holes 23, one-upon each side of the pipe, its

.entire length, these'being for the even and Y uniform distribution of steam from the pipe i 20 into the chamber 6.

Through the bottom 5 of the iron are ay plurality of perforations 24 as common in such devices. passes upwardly through the cover 7 and Acommunicates with a T-connection` 25 which is mounted upon the end of the watersupply 26. Within the T-connection- 25 is a longitudinally reciprocal valve of any desired form and which is well known in the art, the same being opened and closed b reciprocal motion of a protruding stem 2ilnd which stem in this particular case is made to open a' valve when thrust inwardly and to close the valve when thrust outwardly, the latter motion being accomplished by a suitable spiral spring 28, surrounding said stem The water `supply pipe 11 f *I and impinging against the head thereof. An L-shaped lever 29-is pivotally supported at 30 upon one member 31 of the handle 32, the lower finger 33 of which lever is designed to impin e the extreme end of and force inwardly t e valve stem 27 when the horizontal end 34 of the lever is raised. The end 34 of the lever 29 operates within an elongated recess 35 formed within the handle 32 and having a depending fingerknob 36 upon the extreme end thereof protruding below the lowermost edge of the handle 34 becomes readily accesslble to the linger of theoperator and whereby the water supply to the chamber 10 is conveniently governed. j Ivhave shown a horizontal portion 37 intermediate the handle supporting members- 31-31 as bein united with the cover 7 of the iron throug the iron supporting bar 38 which represents an iron designed to be controlled vertically by a mechanism like or similarto that disclosed in my patent dated Aug. 29, 1916, No. 1196112, but it is evident v that this invention is equally applicable to a strictly hand sadiron. While I have shown the heat element as being that of gas, it is evident that by slight modification of construction, the necessary heat may be produced by electricity and that without vdeparting from the novelfeatures of my invention, as it is well known that both gas and electricity have been used for like purposes. A

Any number of openings or holes, as indicated at 39-may be formed lthrough the side or end walls of the iron as required for admitting air forI proper combustion of the gas therein.

In the operation of the device, gas is rst turned on by proper adjustment of the various valves and regulators common in the art and i ited. When the iron is sufficiently heate and the o perator ready to proceed with his work, Just suiicient pressure is brought againstV the linger tip 36 to admit the proper amount of water into the chamber 10 and wherein any portion of the water not immediately generated into steam, will by gravity collect in the rear lowermost por; tion of the receptacle 10 and in no event permit water to through the ottom of the iron unless it is positively desired to do so and in which case a larger volume of water may be admitted to the receptacle for the purpose, or the rearv end of the iron elevated suiiciently to empty ass into the chamber 6 and out the water therein through the pipe 13 into the ch'amber 6. y

Thus it is evident I have provided a comparatively sim le and eilicient means whereby a heated sa iron may be readily sup lied with either steam or water, as desired, or operated independently of either.

Having thus described my invention what I f claim .and desire to secure by Letters Patent, is: p 1. In combination, a two chambered sadiron, an inclined steam generatin receptacle in the uppermost chamber, an having a water supply connected therewith, a steam or Waterdistributing perforated pipe within the lowermost A chamber and connected with the steam generating receptacle, heating means withinl the` iron and above the lowermost chamber whereby both the receptacle and iron are heated and means for controlling the water and heating elements, substantially as described.

2. In combination, a two chambered sadlron, an elongated steam generatin preceptacle in the uppermost chamber an having a water supply connected therewith, a steam or water distributing perforated pipe within the lowermost chamberand connected with thev steam generating receptacle, heating means intermediate the lowermost chamber and the receptaclewhereby both are heated,

means whereby either water or steam or a mixture of both may be admitted to the lowermost chamber, and means for controlling the water and heating elements, substantially as described.

3. The combination with a sadiron hav I tributing chamber whereby an equal distributioxi of heat is accomplished, and means for controlling the water and heating elements, substantially as described.

In testimony whereof I hereunto ailixmy signature in the presence of two witnesses. LOUIS HOFFMAN. Witnesses:
